ORE-SAMPLER.

SPECIFICATION forming part of Letters Patent N o. 684,314, dated October 8, 1901.

Application filed February 25, 1901. Serial No. 48.789. (No model.)

To @ZZ whom, t may concern,.-

Be it known that I, JESSE SCOBEY, a citizen of the United States of America, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Ore-Samplersgand I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, referonce being had to the accompanying drawings, and to thc characters of reference marked thereon, which form a part of this specilication.

My invention relates to improvements in ore-samplers, more especially designed for use in sampling tailings as they are discharged from ore-mills. It may, however, of course be employed in sampling the ore as it is delivered to the mill previous to treatment. My improved sampling mechanism imparts an oscillating movement to the bucket or receptacle, whereby the latter is made to pass quickly through the stream of pulp issuing from the launder at the tail of the mill. The mechanism may be so constructed or regulated that the intervals between strokes or movements of the bucket may be of any desired length. The mechanism is also positive and continuous in its operation and cannot fail to perform its function as long as the mill is in operation. Provision is also made for locking the bucket in position during the period of rest between strokes. This is anv important feature, since the sampling must be done outside the mill, and the bucket is therefore exposed tc the Wind and other influences, which might resultin its movement through the stream of pulp at irregular intervals were it not for this locking feature. Some ore-samplers heretofore used impart a continuous rotation or movement in a circular path to the bucket, causing the same to pass through the stream of pulp once during each revolution. In constructions of this class if the speed of the buckets travel is increased in order to diminish the quantity of ore taken at each passage of the receptacle through the pulp stream the number of passages Will be increased, and hence the quantity of pulp caught for sampling purposes will not be diminished. Moreover, since my apparatus imparts an oscillating movement to the bucket it requires less space for operation than if the movement ofthe bucket were in a circle. This is an advantageous feature in favor of my improved device.

The object of machines of this class is to catch as small a quantity of pulp as possible, providing the quantity caughtfairlyindicates the quality of material discharged as tailings during a given period of time-say twentyfour hours, for instance. Hence my object has been to provide mechanism capable of so manipulating the bucket or receptacle passing through the stream of pulp as to catch a small quantity of the tailings at regular predetermined intervals and which shall be positive and reliable in its action. mechanism is capable of such adjustment that the speed of travel of the bucket through the ore stream may be increased without diminishing the interval between strokes, or the speed of the buckets travel may be increased and the interval between the strokes lengthened at the same time, thus giving au unlimited range of adjustment.

My improved ore-sampler will now beY described in detail, reference being made to the accompanying drawings, in which is illustrated an embodiment thereof.

In the drawings, Figure 1 is a top or plan view of the operating mechanism, the top of the casin g being removed to disclose the parts within.

My improvedV Fig. 9 is 'a perspective view therefrom.

The same reference characters indicate the same parts ,in all the views.

Let the numeral 5 designate a casing,which incloses the operating parts of the mechanism. In this casing and near what l will term the front extremity of the machine is located a stationary vertical shaft 6. Journaled on or loosely engaging the lower extremity of this shaft is a gear 7, operated by a meshing beveled pinion 8, fast on' a shaft 9, journaled in one side of the casing and protruding To the protruding extremity of the shaft 9 is made fast a pulley 10, which may be connected with any suitable power for operating the mechanism.

The upper side of the gear 7 is provided with a pin, stud, or equivalent device 12, which as the gear rotates successively engages radial slots 13, formed in a wheel 13. The periphery or outer edge of the wheel 13 is provided with concavities 13C, located between the outer extremities of the slots 13 and curved to conform to the periphery of the mutilated disk 14, made fast to the center of the gear 7. The disk 14 is cut away, as shown at 14, ou both sides of a radial line passing through the axial centers of the pin 12 and the shaft 6 to give the portion of the wheel 13 located on opposite sides of a slot 13a room to turn when the slot is engaged and therefore actuated by the pin 12 of the gear 7. As shown in the drawings, the wheel13 is provided with four slots 13, and as the gear 7 has only one pin or stud 12 the gear must rotate four times to impart one rotation to the Wheel 13. By virtue of the construction described the curved portion of the disk 14 engages a curve 13c of the wheel13, except vwhen the wheel 13 is in motion. Hence the Wheel13 is locked against turning, except when it is intended to move. It the gear 7 were provided with two pins 12 diametrically located, the wheel 13 would be turned once for every two revolutions of the gear 7, and there would be two spaces 14a in the disk 14, while if the gear 7 were provided with four pins 12 located at equal intervals, or ninety degrees apart, the wheel 13 would rotate in unison with the gear, and there would be no necessity of a disk 14, since a pin of the gear would in that event always be in engagement with a slot of the wheel. The wheel 13 is located in a plane suiciently higher than the plane of the gear 7 to allow the wheel to overlap the gear. As shown in the drawings, the wheel13 is provided with a pin or stud 15, similar tothe stud or pin 12 of the gear 7. This stud 15 successively engages four radial slots 16a of a wheel16, which is of substantially the same construction as the wheel 13, but locatedlin a higher plane. The wheels 13 and 16 are journaled on shafts or spindles 17 and 18, respectively, and supported in their proper planes by collars 19 and 19a. The collar 19 is secured to its shaft by a set-bolt 20. The wheel13 is provided with a cam or mutilated ,disk 21, which is broken away, as shown at 2l, opposite the pin or stud 15 to allow the Wheel 16 Vto turn when actuated by the pin 15. At all other times the wheel 16 is locked from turning by the engagement of the convex periphery of?V the disk 21 with the concave edges 16c of the wheel.

The wheel 16 is provided with a pin 22,whichV successively engages four radial slots 23 of a wheel 23, which is substantially of the same construction as the wheels 13 and 16 and'located direct-ly above the wheel13, being journaled on the same shaft 17 and supported byv a collar 24, made fast to the shaft by a setbolt 25. The wheel 23 is in a higher plane than the wheel16 and so arranged that its,

concave edges 23C are engaged by the convex periphery of a eamdisk 26, fast on the upper surface of the wheel 16 and cut away, as

shown at 26, to allow the wheel 23 to turnV Y Y. 1 when actuated by the pin 22 of the wheel 16.VV

The wheel 23 is provided with two pins 27, which are diametrically located and engageV the radial slots 28 of a wheel 28, which is substantially of the same construction as the V f wheels 13, 16, and 23. The wheel 23 is pro-Y vided with a cam 29, which may be said to be formed from a disk eut away on two oppositeY sides, as shown at29, to allow the wheel 28` Y as the wheel 28 is actuated to alternately ens gage the teeth 32a of a yoke 32. There is a tooth 32, located on each side of the yoke,

which is provided with an elongated opening to permit reciprocation, the gear 31 being located within said opening. The yoke is mounted on stationary spindles 33, secured to the sides of the casing 5 and engaging openings 320, formed in the extremities of the yoke, which moves back and forth upon theY spindles as it is actuated. by the gear 31.

To the front end of the casing is adjust-ably attached a pivot 34. This pivot is fast on a threaded stem 35, passing through a plain opening in the front end of the casing and a similar opening in a depending projection 5,

IIorf formed on the top of the casing. Between the projection 5a and the adjacent wall of the casing is located an adjusting-nut 36, applied to the stem of the pivot, while in front of said projection and applied to the said stem is a lock-nut 37.

A lever 38 is fulcrumed on the pivot 34 and slotted, as shown at 38, to receive a stud 39, formed on one side of the yoke. To the extremity of this lever, remote from the pivot 34, is attached the bucket or receptacle 40,

which by means of the mechanism heretofore described is made to oscillate in front of the discharge extremity of a launder 41. (See Fig. S.)

The speed of travel of the catch-bucket may be regulated by adjusting the stem 35, whereby the pivot 34 is moved forward or back at will. If moved forward or toward the right, referring to Figs. 1 and 2, the bucket will be brought nearer the lever-actuating stud, and the distance of its travel at one stroke will be decreased. Hence its speed of travel for a given stroke of the yokes movement will be diminished. On the other hand, if the pivot 34 be moved rearwardly or toward the left, referring to Figs. 1 and 2, the are or sweep of the buckets travel at each stroke will be increased, and as this stroke must be completed within a given time-namely while the yoke, traveling at a given speed, is making a single stroke ot' predetermined length-the speed of the buckets travel will be increased, and the time required to pass through the stream of pulp will consequently be diminished, and the amount of pulp caught by the bucket at a stroke or movement in one direction will therefore be diminished. This is important, since the smaller the quantity of pulp which it is practicable to catch at each sweep ofthe lever and bucket the smaller the quantity of tailings it will be necessary to handle in order to obtain the desired information and consequently the more satisfactory is a machine of this class.

From the foregoing description the operation of my improved machine will be readily understood. The pulley 10 being rotated by a suitable power, the shaft 9, the pinion 8, and the gear 7 are operated. For each revolution of the gear 7 (assuming that it is provided with asingle pin 12) the wheel13 will be given a quarter-turn, four revolutions of the gear being required to produce one rotation of the wheel. For thesame reason four turns of the wheel 13 are required to give the wheel 16 a single rotation, four turns of the lastnamed wheel to impart a single turn to the wheel 23, two turns of the wheel 23 (since it has two pins 27) to impart a revolution to the wheel 23, and every time the last-named wheel makes a half-turn a stroke or movement in one direction is imparted to the yoke 32, the lever S, and the bucket 40, while for a complete rotation of the'wheel 28 and its gear 3l two strokes or a complete reciprocation is imparted to the yoke and a complete oscillation to the lever and bucket. Hence when the mechanism is constructed and arranged as shown in the drawings the gear 7 must revolve one hundred and twenty-eight times for every rotation of the wheel 2S and its gear 31, or sixty-four times for every stroke of the yoke or passage of the bucket through the stream of pulp issuing from the launder at the tail of the mill. It is evident that by using more pins on the Wheels or by using less wheels, or by resorting toY both of these expedients, the interval between the strokes or movements of the bucket may be diminished, while by using more wheels these intervals may be increased.

The manner of increasing the speed of the buckets travel through the stream of pulp without diminishing the intervals between strokes has already been explained-namely, by moving the pivot 34 farther toward the left, referring to Figs. 1 and 2. This same result may be accomplished in another waynamely, by increasing the speed of the gear '7 and increasing the number of the wheels 13, 16, 23, and 28. It is evident that this increased motion of the mechanism will correspondingly increase the speed of the travel of the yoke, the lever, and the bucket, and consequently diminish the time of the buckets passage through the stream of pulp. It is also evident that by correspondingly increasing the number of the wheels the time between the strokes will not be lessened. Hence it will be seen that my improved construction possesses an unlimited range of adjustment, since the speed of the buckets travel may be increased without diminishing the time between strokes, or, if desired, the speed of the buckcts travel may be increased and the intervals between strokes prolonged at the same time. The reverse of this is also practicable, if for any reason it may be desired. It is also evident that both expedients heretofore explained for increasing the speed of the buckets travel Without diminishing the intervals between strokes may be simultaneously employed.

As shown in Figs. 4 and 5 of the drawings, the slotted wheel is provided with a circular plate A, occupying a plane above its slotted lower portion and upon which the pins A' are mounted. These pins A correspond to the pins or projections l5, 22, and 27 of the slotted wheels 13, 16, and 23. In Fig. 4 four pins A are shown, one being located above the outer extremity of each slot. A wheel of this constructionw-that is, with four pins-would impart a corresponding movement to its corupanion wheel for every movement of its own. The pins 15, 22, and 27 of the slotted Wheels (shown in Figs. 1, 2, and 3) are each mounted on a bridge B, located above the outer extremity of one of the slots of the Wheel and. above the plane of an actuating-pin of another wheel entering the slot. This bridge is attached to or formed integral with the wheel at theoutcr extremity of the slot. (See Fig.2.) It is believed that the form of construction having the continuous plate A is preferable, as it gives great strength to the slotted wheel. The other form is shown in Figs. 1, 2, and 3 to avoid confusion of parts. It must be understood, however, that I do not limit the invention to any special form of construction for supporting the pins on the slotted wheels.

The device 40, termed a bucket or receptacle in the specicatiomis, more properly speaking, a diverting device, since the IIO pulp caught by it while passing through the stream issuing from the launder 41 is merely diverted from the pulp current and discharged or directed into a trough or settlingtank 42, so located that normally the entire pulp stream Would pass over it. (See Fig. 8 of the drawings.)

The operation of the machine is as follows:

Theshaft 9 is rotated by applying power toV the pulley l0 through the instrumentality of a belt 10a. (See Fig. 8.) The movement of the shaft operates the gear 7, since the pinion on the shaft meshes with the gear. As the gear rotates its pin 12 successively engages the slots 13a of the wheel 13 and imparts an intermittent movement to the latter. The pin 15 of the wheel 13 in turn successively engages the slots of the wheel 16 and imparts an intermittent movement to the latter. The pin 22 engages the slots of the wheel 23 and imparts an intermittent movement to the lastnamed Wheel. The pins 27 ot' the wheel 23 engage the slots of the wheel 28 and operate the last-named wheel intermittently. The movement of the wheel 28 operates the mutilated gear 31, which in turn imparts an intermittent reciprocation to the yoke 32, whose pin 39 engages the slot of the lever 38 and imparts an intermittent oscillation to the device 40, which is thereby caused to pass back and forth through the stream of pulp issuing from the launder 31.
